Background

Hydrogen energy is a secondary energy source, which is produced by using other energy sources through a certain method, and is recognized as a clean energy source. The hydrogen gas needs to be detected in the preparation or filling process. The hydrogen detection in the preparation process is mainly used for ensuring the quality of the hydrogen, and the hydrogen detection in the filling process is used for avoiding hydrogen leakage and ensuring the environmental protection and safety of the filling process. In the process of hydrogen detection, the original hydrogen data needs to be collected and stored so as to analyze and process the hydrogen quality, and further the environmental protection and safety of the hydrogen quality and/or the filling process are better guaranteed. The block chain technology has the characteristics of non-tampering, traceability and the like, and the original hydrogen data are stored through the block chain technology, so that the original hydrogen data can be prevented from being illegally tampered by others, and the acquired historical original hydrogen data can be searched and traced.

Due to the different computing capacities of the servers of different block nodes in the block chain, the speed of the servers for acquiring the encrypted original hydrogen data and decrypting the encrypted data is greatly different. Although the existing hydrogen detection system can perform uplink operation on the collected original hydrogen data through a block chain technology to better ensure the hydrogen quality and/or the environmental protection and safety of the filling process, the existing hydrogen detection system cannot well coordinate the computing capability of different servers, and the query and acquisition speed of encrypted data is low and needs to be improved.

As shown in fig. 1 and 2, a hydrogen gas detection system based on cloud servers includes a block chain network composed of a plurality of background cloud servers and a plurality of hydrogen energy sites, where the plurality of hydrogen energy sites are in one-to-one correspondence with the plurality of background cloud servers.

The hydrogen energy station comprises a plurality of first front-end data detection modules which are respectively installed at different sampling node positions, and the first front-end data detection modules are used for detecting original hydrogen data and transmitting the original hydrogen data to the background cloud server.

Of course, each background cloud server may also correspond to at least two hydrogen energy source sites, and any one hydrogen energy source site corresponds to only one background cloud server. Therefore, original hydrogen data of a plurality of different hydrogen energy sites can be collected through the background cloud server.

The background cloud servers comprise instruction modules, search modules, uplink modules, identification modules, decryption modules, first private keys, first public keys, second private keys and second public keys, the instruction modules are used for generating uplink request instructions, the first private keys and the first public keys of the background cloud servers are generated through the same key generation algorithm, the second private keys and the second public keys of the background cloud servers are generated through different key generation algorithms respectively, the identification modules are used for screening original hydrogen data through the consensus algorithm, the uplink modules are used for encrypting the original hydrogen data screened through the consensus algorithm into first encrypted data by using the first public keys after identity information of uplink requesters is verified, and publishing the second encrypted data to the block chain network and the original hydrogen data screened through the consensus algorithm into second encrypted data by using the second public keys A blockchain network.

The uplink requester may be a developer of the hydrogen detection system. The uplink requester transmits the public key to the background cloud server and signs the identity information by using the private key, and then the uplink module verifies the identity information of the uplink requester by using the public key of the uplink requester. The original hydrogen data is encrypted into first encrypted data or second encrypted data, and the first encrypted data and the second encrypted data are issued to the blockchain network, so that the safety, reliability and authenticity of the original hydrogen data can be guaranteed by utilizing the characteristic that blockchain technical data cannot be tampered.

The first private key is paired with the first public key, the second private key is paired with the second public key, the first private keys and the first public keys of the background cloud servers are the same, and the second private key and the second public key of each background cloud server are different. The background cloud server further comprises a storage module, and the first private key, the first public key, the second private key and the second public key are stored in the storage module of the background cloud server.

The original hydrogen data screened by the consensus algorithm are shared data and do not relate to core secrets, and the original hydrogen data not screened by the consensus algorithm are core data and do not participate in data sharing.

The search module is used for randomly traversing all blocks of a certain block node in a search block chain network after receiving a data query request, acquiring encrypted data matched with the data query request and sending the encrypted data to the identification module, the identification module is used for identifying and judging whether the encrypted data is first encrypted data or second encrypted data, and the decryption module is used for decrypting the first encrypted data matched with the data query request by using a first private key and decrypting the second encrypted data matched with the data query request by using a second private key and sending original hydrogen data contained in the decrypted first encrypted data and the decrypted second encrypted data to a user side. That is to say, after the decryption of the first encrypted data or the second encrypted data is completed, a certain background cloud server establishes communication connection with the user side matched with the data query request, and sends the original hydrogen data contained in the decrypted first encrypted data or the decrypted second encrypted data to the user side.

And after receiving a data query request sent by a user side, a search module of one background cloud server issues the data query request to the block chain network, and other background cloud servers in the block chain network randomly traverse all blocks of a certain block node in the block chain network according to the data query request to acquire encrypted data matched with the data query request.

When a certain background cloud server in the block chain network searches encrypted data matched with the data query request in a traversing manner, whether the encrypted data is first encrypted data or not is judged, if the encrypted data is the first encrypted data, the first encrypted data is decrypted, a decryption completion signal is issued to the block chain network after decryption of the first encrypted data is completed, and traversing searching or decrypting actions are stopped after other background cloud servers in the block chain network receive the decryption completion signal.

In other words, if the encrypted data is the first encrypted data, it means that the encrypted data to be queried by the user is the shared data, and all the background cloud servers in the blockchain network can decrypt the first encrypted data by using the first private key and send the original hydrogen data included in the decrypted first encrypted data to the user. When one background cloud server completes decryption of the first encrypted data, a first encrypted data decryption completion signal can be sent to the blockchain network to enable the rest background cloud servers to stop traversing searching or decryption actions, so that the memories and computing power of the rest background cloud servers are released, and the comprehensive performance and the overall computing power of all the background cloud servers of the whole blockchain network are improved.

If the encrypted data is the second encrypted data, it means that the encrypted data to be queried by the user side does not belong to the shared data, and only one background cloud server in the blockchain network can decrypt the second encrypted data by using the corresponding second private key. And if one background cloud server recognizes and judges that the second encrypted data cannot be decrypted through the second private key of the background cloud server, stopping the current decryption action, packaging and binding background cloud server information corresponding to the second encrypted data and the data query request, and then sending the background cloud server information and the data query request to the block chain network. And the other background cloud servers receive the packaged and bound background cloud server information and the data query request, if the background cloud server information is consistent with the self information, the traversal search or decryption action of the second encrypted information is continuously completed, and if the background cloud server information is inconsistent with the self information, the current traversal search or decryption action is stopped. Therefore, by sending the background cloud server information and the data query request corresponding to the second encrypted data to the blockchain network, the memory and the computing power of the rest background cloud servers can be further released, and the comprehensive performance and the overall computing power of all background cloud servers of the whole blockchain network are improved.

The uplink request instruction comprises identity information of an uplink requester, the data query request is sent to the background cloud servers by the user side, and the user side is bound with at least one background cloud server. When the user side sends a data query request, the background cloud server firstly acquires user side identity information and verifies the user side permission level according to the user side identity information, if the user side has the data query request permission, the background cloud server sends the data query request to the search module, and selectively sends original hydrogen data contained in the decrypted first encrypted data or second encrypted data to the user side according to the user side permission level.

When the encrypted data corresponding to the data query request sent by the user side does not relate to the business core secret, all background cloud servers in the block chain network are called to perform traversal search and decryption on the encrypted data, so that the problems that the encrypted data cannot be rapidly traversed and searched and decrypted due to the fact that the computing capacity of one background cloud server is insufficient, the rest background cloud servers are in an idle state, and the computing capacity cannot be effectively utilized can be solved.

To sum up, the cloud server-based hydrogen detection system configures two sets of keys (namely, a first private key, a first public key, a second private key and a second public key) in different background cloud servers, and respectively encrypts and decrypts the original hydrogen data which passes through the screening and does not pass through the screening by using the two sets of keys, so that the computing capabilities of the different background cloud servers can be well coordinated to search and decrypt the encrypted data requested to be queried by the user, the problems that the existing hydrogen detection system cannot well coordinate the computing capabilities of the different servers, the query speed and the efficiency of acquiring the encrypted data are low are solved, and the query and acquisition speed of the encrypted data can be improved.

The analysis module stores a core algorithm and processes the raw hydrogen data by using the core algorithm to analyze the hydrogen quality. Since the core algorithm is a conventional technical means in the art, it is not described herein in detail.

The first front-end data detection module is located at the hydrogen energy station and used for detecting original hydrogen data, the analysis module stores a core algorithm and is used for processing the original hydrogen data by utilizing the core algorithm to analyze the hydrogen quality, and the hydrogen energy station is separated from the background cloud server, so that the core algorithm can be protected, and the hydrogen detection system is prevented from being violently cracked by others and simulated and copied after sale.

The hydrogen energy site is responsible for detecting and collecting original hydrogen data, the original hydrogen data are delivered to the background cloud server to be stored and processed so as to analyze the hydrogen quality, the structure and the cost of the hydrogen energy site can be simplified, industrialization can be better achieved, and the hydrogen energy site can be remotely and intelligently controlled through the background cloud server.
